I vote for anything with esters in it...

I've used both. HDEO has the edge imo, even though the euro was edge...

Same here. Go RedLine oils!

They're both much the same, I'd wager, at least as far as we could tell outside a lab. An A3/B4 oil is, after all, dual rated, and is certainly acceptable for use in various pre-emissions diesel engines. But, you're not going to run a bunch of quick, cheap oil changes on a synthetic A3/B4 versus a conventional 15w-40, either.

Neither did any cleaning of any measurable amount in my past experience w/ them. That's how I got sucked into the additive vortex.

^^^ This is the correct answer

Keeping a motor clean or cleaning a motor known to have sludge?
Two different things

HDEO will often meet ACEA E-series specifications.
